We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
A cheap Carbon Capture breakthrough? MOF molecular cages that trap CO2
Carbon Capture is the Transition’s great unknown. Big targets have been set but nobody knows how we’re going to meet them. It's clear we need utility-scale breakthroughs, and fast. And cheap. We take a look at one example of cutting edge research that could deliver both. Scientists at the U.S. Department of Energy’s SLAC Laboratory and Stanford University have taken the first images of CO2 molecules captured within a highly porous nanoparticle … [Read more...]
Solar intermittency: upbeat “annual” carbon reduction estimates miss the “hourly” reality
There is a maximum speed at which solar capacity can expand. You know you’ve passed it when insufficient storage means solar curtailment, or selling the daytime excess means curtailment of other clean energy generators. As solar grows, so too will this problem. Vincent Xia, at the Precourt Institute for Energy, Stanford University, reports on a new Stanford study which says emissions predictions are not taking this into account, thus … [Read more...]
UK oil & gas keeps rising. Clean Energy blueprint can reverse it
In the UK the £2.3bn (=$2.9bn / €2.6bn) in new oil and gas subsidies introduced since 2014 will state-fund the addition of twice as much carbon as its coal phaseout saves, says a new report “Sea Change: Climate Emergency, Jobs and Managing the Phase-out of UK Oil and Gas Extraction”. Can the UK call itself a climate leader if its existing policies push it over its emissions limits? It can, if you consider this: the UK took 16 years to become the … [Read more...]
1.5°C: IEA’s scenarios will fail, need urgent review says letter from experts, business leaders
The letter’s signatories – experts, business leaders, politicians and more - call on the IEA to make the 1.5°C target the central scenario in its highly influential annual World Energy Outlook. At present, its “New Policies Scenario” puts us on track for between 2.7°C and 3.3°C. That's a problem, because too many energy decision-makers cite it as an acceptable guide, making it a self-fulfilling prophecy. Even the “Sustainable Development … [Read more...]
Climate Auctions can reduce emissions and accelerate regulatory, financial and infrastructure goals
Auctions for delivering an amount of power at a defined price are already well established for renewables. “Climate Auctions” do the same with carbon emissions: a carbon price is guaranteed to the winning bidder, but only paid on delivery of the emissions cut. Tyeler Matsuo and Julia Meisel at Rocky Mountain Institute say this is proving particularly useful in emerging and developing countries where progress in building up their climate laws is … [Read more...]
GGFI: “Avoid carbon bubble, choose financial centre wisely”
We already have indexes that pick green stocks, and rank nations by their policies. The Global Green Finance Index (GGFI) ranks the world’s financial centres – London, New York, Singapore, Shanghai, etc. – by the policies and support they give to green investments. Old ways of valuing assets, particularly in fossil fuel companies, are being questioned say Mike Wardle and Michael Mainelli of the think tank Z/Yen, one of the creators of the index. … [Read more...]
Investing in gas: the effect of carbon taxes, gas prices, and the growth of renewables
Schalk Cloete presents his latest article looking at what affects the profitability of an investment in a specific power sector. After reviewing onshore wind, nuclear and solar, he now looks at gas. His analysis of coal is to come. The major variables are increasing CO2 prices, and natural gas pricing. He adds that the growth of wind and solar should benefit load-following gas power plants: they are plugging the intermittency gap when electricity … [Read more...]
Energy as a service: light, heat, mobility, information
Large scale electricity generators, unconcerned with end-use, want to sell you more electricity, argues Walt Patterson of the Hoffmann Centre for Sustainable Resource Economy, based at Chatham House. But the arrival of small-scale, localised and micro-grid suppliers could see the electricity generation business turned on its head. It opens the door to the selling of the service – light, heat, refrigeration, motive power, information – rather than … [Read more...]
New tool to show whether companies’ climate strategy matches their public ambitions
By now we’re used to stats that show what would happen if everyone in the world had the same carbon footprint as a European, or an American, someone in China, or indeed anywhere. According to the consultancy right. based on science, they have now created a way of modelling the same projections, except for specific companies. The model also number-crunches a company's climate strategy to work out whether they are going to help or hinder the race … [Read more...]
The compelling case for carbon capture and storage
By 2040 60% of primary energy will still come from fossil fuels, says the IEA. That means Carbon Capture and Storage (CCS) must be part of the technology mix to hold back climate change. Yet today there are only 18 CCS facilities in operation, with 25 in the pipeline. We’ll need at least 2,000 by 2040. Brad Page, CEO of the Global CCS Institute, lays out the reasons why we have no time to lose. The World Economic Forum’s meeting in Davos … [Read more...]
A grassroots fightback against Trump and U.S. Oil & Gas is underway
As the 116th Congress commences, in the wake of dire reports from climate scientists, the debate over U.S. climate policies has taken a welcome turn towards bold solutions. Capitol Hill is alive once again with policy proposals that edge towards the scale required to address the crisis we’re in. A new study by Kelly Trout of Oil Change International, along with 17 partner organisations, makes it clear that managing a rapid and equitable decline … [Read more...]
